Hydrogen and Energy Intensity and Utilization

This nascent hydrogen segment explains it in terms of energy intensity and utilization. Valery Miftakhov from ZeroAvia, developers of zero-emission powertrains for aircraft powered by hydrogen, says aircraft have much higher energy intensity and utilization than cars. As such, they should be the focus of attention for hydrogen backers.

In an article for Aeronautics Online, Miftakhov compared intensity and utilization rates for cars and aircraft, in other words the portion of the vehicle’s weight dedicated to fuel and the amount of time it spends in motion. Cars, he said, have an energy intensity average of some 2 percent and energy utilization rates of about 5 percent. A Boeing 737, on the other hand, has an energy intensity average of close to 40 percent and a capacity utilization average of 40 percent, spending about 10 hours daily in the air.

The Science Behind Molecular Hydrogen Tablets




Synopsis of ACT’s Current Technology

ACT’s original technology began with an idea to make hydrogen using the least amount of energy. This brought about the cell with twenty-five plates and with an array of plates consisting of low impedance as a focus. This brought us to the cell that produces one kilogram of hydrogen for approximately sixty cents using fifteen cents per kiloWatt as a basis of grid power cost.

After years of perfecting the design, it became apparent that the most critical factor was generating a plasma field. This was difficult as five separate factors had to all be in sync, which meant when one or more of the five factors changed the others would have to change or be compensated to maintain the production of plasma.

We now have a process focusing on producing a plasma easily without the complexity of so many factors to maintain. This is an arc plasma process that creates a medium where the production of hydrogen can be from water breaking apart due to extremely high temperature as well as ionic bonds being broken. The process still involves an anode and cathode based design but with different cathode features due to the cathode being produced from a plasma field induction design. With this process, more possibilities of variations in hydrogen output mainly the separation of hydrogen and oxygen at the point of production can be obtained not being limited to HHO gas output. This eliminates the need for an additional process such as pressure swing adsorption of cryogenics to separate the hydrogen from the oxygen. In addition to this, the output of hydrogen is of high purity only requiring filtration such as palladium membrane to achieve hydrogen purity required for hydrogen fuel cell application as well as other applications requiring high purity. Storage of hydrogen in a compressed form can be achieved at the point of production.

The original technology is still above and beyond electrolysis or steam reformation of methanol however, the new technology has many more application possibilities.
